Amtech flux for reballing

[uligli]

I am going to buy a tube of Amtech flux on ebay, but there are 4 kinds for reballing, don't know which one is better for BGA reballing, any suggestion?

Amtech Gel Flux NC-559-V2-TF for BGA Rework
Amtech Gel Flux 4300/LF-4300-TF BGA Rework
Amtech Gel Flux RMA-223-TF for BGA Rework
Amtech Gel Flux SYNTECH-TF for BGA Rework

Definitely get a no clean as you are not going to clean under the BGA!

Amtech Gel Flux 4300/LF-4300-TF is what I am using with no problems, it is reckoned to be the one to go for by those in the know.

Re: Amtech flux for reballing

The 559 version seems to be the best. At least that's what the professionals use.

Just try to avoid knockoffs..Everything below $15(for 10cc) isn't genuine..

Re: Amtech flux for reballing

I use RMA-223 and it works great for the reball process! This flux is made in the USA so whatever you do, don't buy it from Japan or China. You will most likely be buying fake flux! Also another good company is Kingbo I have the RMA-218 and I like it for reballing but prefer Amtech but it's GREAT for just about everything else. Any which way you look at it if you're going with a no-clean Amtech flux you're getting a GREAT product, just make sure you buy it from a seller in the USA. Again, it's made here there is no reason to go out of the country for it!

Yesterday i took more time to take a look on ebay, there are sellers from US & Canada selling the fake ones on ebay. I do a lot of research about the product and the seller before buying anything on ebay

Here is a detailed article about fake/genuine:

Re: Amtech flux for reballing

Where do you recommend getting 'Flux' from?
I noticed DigiKey carries flux but none of the two aforementioned brands; is the flux from them not good or recommended?
I'm about to do my first MB recap and would like to try using flux besides whats in the solder.

Re: Amtech flux for reballing

Wish I knew of the stuff I was using at Sony warranty, they took the dam stickers off the bottles. GITS!.. no residue and perfect for re-balling.

And Bucherest is an awesome place to live, I know because I drove around using the Google car!.

Re: Amtech flux for reballing

I am using the 559 too.. Tried the 223 but 559 is better. Avoiding the fake ones is a bit tricky.

Amtech Gel Flux 4300/LF-4300-TF BGA Rework
remember you only need a very small amount for best results, too much and your solder balls will be all over the place
